We introduce the "Dirac similarity principle" that states that only thosepoint-like Dirac particles which can interact with the Dirac electron can beobserved, such as in the Standard Model. We emphasize that the existing worldof the Standard Model is a Dirac world satisfying the Dirac similarityprinciple and believe that the immediate extension of the Standard Model willremain to be so. On the other hand, we are looking for Higgs particles for thelast forty years but something is yet to be found. This leads naturally to the"minimum Higgs hypotheses".  Now we know firmly that neutrinos have tiny masses, but in the minimalStandard Model there is no natural sources for such tiny masses. If nothingelse, this could be taken as the clue as the signature of the existence of theextra heavy $Z^{\prime 0}$ since it requires the extra Higgs field, that wouldhelp in generating the neutrino tiny masses. Alternatively, we may have missedthe right-hand sector for some reason. A simplified version of the left-rightsymmetric electroweak model has the simplest Higgs sector (in which there isone standard left-hand Higgs doublet together with the image right-handed Higgsdoublet), of which the Higgs sector also satisfies the "minimum Higgshypothesis". Or, if we question the origin of the family symmetry, we mayconsider to enlarge it to the family gauge symmetry. It transpires very feeblefamily interactions. All the above possibilities satisfy both the so-called"Dirac similarity principle", the "minimum Higgs hypothesis", andrenormalizability.
